I am trying to connect to AWS IOT using X.509 certificate authentication but I am getting SSL Exception in PEM lib and not able to figure out what's going wrong have done the initialization and configuration as per the documentation.
I am using ats endpoint.

Client Initialization:
myAWSIoTMQTTClient = AWSIoTMQTTClient(CLIENT_ID)
myAWSIoTMQTTClient.configureEndpoint(ENDPOINT, 8883)
myAWSIoTMQTTClient.configureCredentials(PATH_TO_ROOT, PATH_TO_KEY, PATH_TO_CERT)
myAWSIoTMQTTClient.connect()
print("mqtt client connection successful")

Traceback:
in connect_aws_iot_client
myAWSIoTMQTTClient.connect()

How did you generate your certificate? There is a similar error where the solution was that the private key was not correct.

[Shivam-Kukreja]

Yes my private key was incorrect I was just saving the key only in the file, was missing Begin and End Private key lines in the file("-----BEGIN RSA PRIVATE KEY-----")

Thanks for the help.
